So just got an email from John, and my Suppressor adapter for my Trail NP XL should be here by this weekend. Excited to see if the improvements change the performance as much as I hope, but not sure if I should use blue loctite or not. The original end caps were plastic, and the new adapter is obviously milled from steel. I will need to clean the threads on the barrel thoroughly to get the bits of plastic up, and frankly to clean up poor lathe work from the Benjamin factory. I will probably remove the adapter for barrel cleaning. So my first instinct is actually to use anti-seize, but thought I would see what the collective thinks before it gets here.
